The Potash is all obtained from the Stasstfurt Potash 
salts, especially Sulphate of Potash, Muriate of Potash aad 
Kainit. The sulphate is used almost entirely for cacao at 
the present time but general experience in the West Indies 
indicate that muriate is the more effective, especialiy on the 
heavier soils, and probably that form will be used more 
extensively in the future. 
All fertilizers contain or should contain these three ele- 
ments, nitrogen, phosphorous and potasium, in the most 
suitable form and in the proportions needed by the tree 
at the time the fertilizer is appled. A young tree or a 
dormant, neglected tree needs proportionately more ni*rc 
gen while a tree in good condition needs proportionately 
more potash and phosphoric acid. The following forniulas 
are examples of what may be expected to give good results: 
No. 1.—For Young Trees or Old Neglected Trees. 
Muriate of Potash. . . 40 Ibs. 6% potash 
Basie Slag 3.54, cree LOOr 6% phosphorie acid 
Nitrate of Soda... . 200 ,, 9.4 Yo nitrogen 
Apply from one pound per tree on small trees to 10 pounds 
per tree for large old trees. 
No. 2.—For Young Trees Beginning to Bear or Old Trees in Fairly 
Good Growing Condition. 
Muriate of Potash. . . 40 Ibs. 7 Yo Potash 
Basic Slag. . . . . . 200 , 79, phosphoric acid 
Nitrate of Soda. . . . 150 |, 83 oO nitrogen 
Apply from two to three pounds per young tree, ac- 
cording to size, and about ten pounds per old tree of good 
size. 
No. 3.—For Bearing Trees in a New Plantation or Trees in Old 
Plantation Having Previously Had Former Applications. 
Muriate of Potash. . . 50 Ibs. 10 QJ, potash 
Basic-Slag. 3. s-«- 100 oy 8% phosphoric acid 
= 
Nitrate of Soda. . . . 100 » 6.4 GY nitrogen
